Abstract: The carbon dioxide filter system includes a reservoir, a solvent, an injector coupled to the reservoir, an exhaust port, and a collection chamber. The solvent is disposed in the reservoir. The injector, the exhaust port, and the collection chamber are each coupled to the reservoir. The solvent includes a hydroxide. The injector includes a fan configured to direct polluted air containing carbon dioxide to the reservoir. The polluted air containing carbon dioxide reacts with the hydroxide of the solvent. The reaction may separate the carbon dioxide from the air, thus forming a liquid filter. The reaction produces a by-product that is separable from the solvent.

Abstract: Carbon-sequestering composite mixture and methods of carbon sequestration utilizing an aquatic composite structure composed of the composite mixture. The mixture comprises a composite, nanoparticles, and binder. The nanoparticles impact the pore size of the composite mixture, thereby positively impacting the carbon sequestration properties of the mixture. By emplacing an aquatic composite structure composed of such a mixture in an aquatic environment such that it provides erosion mitigation, simultaneous environmental protection effects may be achieved. Further, the binder positively encourages natural ecological growth on the aquatic composite structure, thereby encouraging environmental restoration and encouraging naturally-occurring carbon sequestration from the ecological growth, potentially well past the point at which the aquatic composite structure is unable to continue to sequester carbon.

Abstract: A disinfectant sprayer assembly, including a tank defining a volume, a disinfectant suspension contained within the volume, a nozzle having a size variable spray opening, a pump operationally connected to the volume and to the nozzle for pumping disinfectant from the volume through the spray opening to apply disinfecting to a predetermine surface having a predetermined set of physical characteristics for a period of time, an ion generator operationally connected to the volume for ionizing the disinfectant suspension, and a microprocessor operationally connected to the size variable spray opening. The ion generator voltage, spray opening size, and distance between the predetermined surface and the spray opening are predetermined based on the predetermined set of physical characteristics of the surface.

A filter containing at least one porous hydrophobic and lipophobic layer, at least one diamond like carbon coated copper layer interposed between two non-woven fabric layers, and at least one additional non- woven fabric layer. A filter comprising at least one porous hydrophobic and lipophobic layer, at least one diamond - like carbon coated copper layer, and at least one non - woven fabric layer, the at least diamond-like carbon coated layer is between the at least one porous hydrophobic and lipophobic layer and at least one non - woven fabric layer.

Abstract: Methods of enhancing the anti-virus capabilities of surfaces directly contacted by humans. The methods include applying a hydrophobic coating material to a surface of an article to form a hydrophobic surface coating overlying the surface such that the hydrophobic surface coating defines a hydrophobic outer surface of the article. The hydrophobic outer surface is more hydrophobic than the surface of the article, and a liquid that contains suspended viruses and is deposited on the hydrophobic outer surface exhibits a contact angle relative to the hydrophobic outer surface that is greater than a contact angle of the liquid if directly deposited on the surface of the article, and the hydrophobic outer surface thereby increases inactivation of the viruses suspended in the liquid as compared to the surface of the article to which the hydrophobic coating material was applied.

Abstract: A coating apparatus for the reduction of aerodynamic noise and vibrations. The coating apparatus is configured to include a group of fibrillar structures, wherein each fibrillar structure is configured with a diverging tip so that the coating reduces the size of and shifts downstream, a separation bubble, and modulates large-scale recirculating motion. Each fibrillar structure can be configured as a cylindrical micropillar. The group of fibrillar structures can be configured as a group of uniformly distributed cylindrical micropillars (e.g., one or more micropillar arrays). The surface coating is effective in reducing the separation bubble and displacing the separation bubble downstream. The coating facilitates a reduction in noise (e.g., aerodynamic noise) and vibrations due to the reduction in the size of the separation bubble.

Abstract: An aerodynamic or hydrodynamic wall surface has an array of fibrillar structures disposed on and extending from the wall surface, wherein each fibrillar structure comprises a stalk and a tip. The stalk has a first end and a second end, wherein the first end is attached to the wall surface, and the stalk is oriented with respect to the wall surface at a stalk angle between approximately 1 degrees and 179 degrees. The tip has a first side and a second side, wherein the first side is attached proximate to the second end of the stalk, the tip has a larger cross-sectional area than the stalk, and the second side comprises a substantially planar surface that is oriented with respect to the stalk at a tip angle between approximately 0 degrees and 90 degrees.
